First of all, domain level separation would be really great. (it makes sense, because there already email which are also domain related)

Then we could maybe have "favorite" apps, appearing on top.

Renaming app would be useful, if this could be taken into account also in the notifications: sometimes we have the docker ID of the app, but it isn't always really helpful when there's no context added.

Related to the same page, it would be helpful to have a different tile color for apps which are crashed or in a bad state. Right now if I see an app with ID has crashed alert, I have to scroll through all my apps to find the correct one.
